Tibial bowing in children - what is normal? A radiographic study.

Purpose: To define osseous landmarks on tibia radiographs in order to establish age-related normal values characterizing physiological tibial bowing in children.

Materials And Methods: Five hundred and twenty-six patients aged 0-17 years with normal radiographs of the lower legs were identified and retrospectively reviewed by two blinded radiologists. In anteroposterior (ap)/lateral (lat)-views, 3 lines defined tibial length and angulation.

Incarcerated obturator hernia-laparoscopic repair with intraoperative view of the corona mortis.

Obturator hernias are a rare form of abdominal wall hernias. We present a case of a patient with an obturator hernia diagnosed by the classical signs of lower abdominal pain, a positive Howship-Romberg sign (painful internal rotation of the hip) and a computed tomography scan showing a herniated loop of small bowel. During the emergency laparoscopic hernia repair (transabdominal preperitoneal approach) a variant vessel, the corona mortis, was detected.
